5.1 GENERAL SAFETY INSTRUCTIONS FOR POWER TOOL USE
When using any type of power tool there are steps that should be taken to make sure that you, as
the user, remain safe.
Common sense and a respect for the tool will help reduce the risk of injury.
Read the instruction manual fully. Do not attempt any operation until you have read and
understood this manual.
Most important you must know how to safely start and stop this machine, especially in an
emergency.
Keep the work area tidy and clean.
Attempting to clear clutter from around the machine during
use will reduce your concentration. Mess on the floor creates a trip hazard. Any liquid spilt on the
floor could result in you slipping.
Find a suitable location.
If the machine is bench mounted; the location should provide good
natural light or artificial lighting as a replacement. Avoid damp and dusty locations as it will have
a negative effect on the machine’s performance. If the machine is portable; do not expose the tool
to rain. In all cases do not operate power tools near any flammable materials.
Beware of electric shock.
Avoid contact with earthed surfaces; because they can conduct electricity
if there is an electrical fault with the power tool. Always protect the power cable and route it
away from danger.
Keep bystanders away.
Children, onlookers and passers by must be restricted from entering the
work area for their own protection. The barrier must extend a suitable distance from the tool user.
Unplug and house all power tools that are not in use.
A power tool should never be left
unattended while connected to the power supply. They must be housed in a suitable location,
away locked up and from children.
Do not overload or misuse the tool.
All tools are designed for a purpose and are limited to what
they are capable of doing. Do not attempt to use a power tool (or adapt it in any way) for an
application it is not designed for. Select a tool appropriate for the size of the job. Overloading a
tool will result in tool failure and user injury: This covers the use of accessories.
Dress properly.
Loose clothing, long hair and jewellery are all dangerous because they can become
entangled in moving machinery: This can also result in parts of body being pulled into the
machine. Clothing should be close fitted, with any long hair tied back and jewellery and neck ties
removed. Footwear must be fully enclosed and have a nonslip sole.
Wear personal protective equipment (PPE).
Dust, noise, vibration and swarf can all be dangerous if
not suitably protected against. If the work involving the power tool creates dust or fumes; wear a
dust mask. Vibration to the hand, caused by operating some tools for longer periods must be
protected against. Wear vibration reducing gloves and allow long breaks between uses. Protect
against dust and swarf by wearing approved safety goggles or a face shield. These are some of the
more common hazards and preventions; however, always find out what hazards are associated
with the machine/work process and wear the most suitable protective equipment available.
Do not breathe contaminated air.
If the work creates dust or fumes; connect the machine (if
possible) to an extraction system either locally or remotely. Working outdoors can also help if
possible.
Move the machine as instructed.
If the machine is hand held, do not carry it by the power supply
cable. If the product is heavy; employ a second or third person to help move it safely or use a
mechanical device. Always refer to the instructions for the correct method.
Do not overreach.
Extending your body too far can result in a loss of balance and you falling. This
could be from a height or onto a machine and will result in injury.
Maintain your tools correctly.
A well maintained tool will do the job safely. Replace any damaged
or missing parts immediately with original parts from the manufacturer. As applicable; keep blades
sharp; moving parts clean, oiled or greased; handles clean; and emergency devices working.

wheel side covers then take off covers.
3. Insert spindle lock tool, holding the spindle in a
fixed position use a screwdriver then remove the
nut and flange.
NOTE: The grinding wheel nut has a left thread.
4. When fitting a new grinding wheel always check
that the stated max. grinding wheel RPM exceeds the RPM of the bench grinder. Also
check the grinding wheel for damage such as flaws or cracks, then if the wheel appears
satisfactory, fit the new wheel to the grinder.
5. Remove the old wheel and replace it with the new one.
6. Place the flange on the spindle and tighten the spindle nut just enough to hold the
wheel firmly.
Do not over tighten the nut as the wheel may become damaged.
Repeat
the above to replace the opposite wheel.
7. Re-assemble the side covers.
